I quit looking when I saw this:
Online Bids - 15% Buyer's Premium
Phone Bids - 13% Buyer's Premium
Live In-Person Bids - 10% Buyer's Premium
Minimum Buyers Fee: $300 Minimum Buyers Fee or 10% / 15% per item (whichever is greater) on all motorcycle, car, and truck purchases
Auctioneers already get a cut of the sale dollars then charge a buyer's premium; I chose to not participate.

yah, it varies on auctioneer fees. I contacted 2 local small auctioneers nearby me when was thinking of having an auction to sell my mom's house and stuff. One wanted a flat fee while the other wanted 5% fee added to all items sold, including the house. I thought that was a bit much, but at least the house fees and most others were the BUYER would pay, not me the seller.
